Tableau Software on Thursday reported a strong second quarter in sales, with $90 million in revenue, up more than 81 percent from the same quarter last year.

Tableau (NYSE: DATA) added 2,200 new accounts and had 157 sales worth more than $100,000, the company reported. Despite that, Tableau reported growing losses: The company showed a net loss of more than $4.5 million in the quarter, an increase of 77 percent in its loss year-over-year.

The company also reported more than 100 percent growth in international sales.

Wall Street responded favorably despite the loss. Shares spiked more than 5 percent in after-hours trading to around $68 per share.

Tableau recently released a new version of its data visualization software, including the long-anticipated version for Apple computers. The company has expanded in its space along what's been dubbed the "Silicon Canal" in Seattle's Fremont neighborhood (next door to Google's Seattle office) and is looking for an additional 275,000 square feet, according to real estate broker Jones Lang LaSalle.
